To all 'whom 'iltmayconcerm 1 v Be it known that I, Tummy E'. Boex, a

citizen of the United States, lresidin cago, in the county of `Cook andtate of Illinois, have invented a certain new and useful Waste-SteamDetector and Recorder,l

of which the following is a specification.

My invention relates to mec anism for detecting the waste of steam fromsteam boilers, more particularly locomotive boilers, such mechanismbeing exemplified by Zerbee Patent No. 1,027,368 dated May 21, 1912. Theobject of my invention is to provide the mechanism or device with meansfor permanently recording the time of the blowing-off of the steam valvesuch as the safety valve as well as the time of normal condition of.

the valve, so that not only may the actual time of the blow-off beregistered but also the particular locality or localities along theroad, in case of a locomotive, where the steam blew off. Another objectof my invention" is to provide a simple, eiicient and reliable device ofthe character referred to.

In/the drawing, Figure 1 is an elevation of my device shown attached toa safety valve and illustrating the door of the casing open; Fig. 2 asectional plan on the line 2- of Fig. 1; Fig. 3 a detail view of aportion of the clock movement and the recording strip mechanism.

Referring to the present embodiment of my invention as herein shown theoperating parts are mounted in and for the most part inclosed by a boxor casing 1 of suitable size and dimensions and having at one side aclosure or door 2 which is provided with locking and sealing, such asthe hasp 3, staple 4 and any suitable lock (not shown) in order toprevent entrance to the interior of fthe casing by any unauthorizedperson. By preference this casing is adapted to be removably secured tothe safety valve such as the one shown at 5 and to this endand as hereinshown the casing is provided with a bracket 6 which partiallyencompasses the cylindrical body of the safety valve and is securedthereto by means `A lever 9 1s pivoted to the casing in suitable manneras upon the pin 10, the lever extending into the casing and alsoextraneous thereof, its outer end being provided with an enlarged orfan-tailed plate portion 11 which extends over some of the openings 5lof the safety valve in position to receive The registerin the :impact ofthe escaping steam and to be'thereby-moved upwardly. In order to limitboth the upward and downward movements of the lever the casing is'provided with a lower stop 12 and an upper stop 13 projectinghorizontally adjacent the lower and upper edges respectively of thellever.

mechanism may, in the the invention, be of any suitable and desiredconstruction adapted to coperate with the movements of the pencil toeiect a permanent record. 'In the present instance this mechanismcomprises a suitable time movement 15 contained Within the broadei`aspect o casing and including a driven spindle 16 on which is mounted atime Wheel 17. Two rolls 18 and 19 are pivotally mounted on a carrierplate 20 which is pivoted to the top of the clock movement by means ofthe bearing pin or spindle 21 on which the roll 18 rotates. A chart orrecording strip 22 is carried on and between these two rolls 18 and 19,the former being the supply or unwindu ing roll and the other theWinding roll. The strip is fed synchronously by means of the f clockmovement through the medium of the time wheel 17 against which theWinding roll 19 and the strip are held in yielding frictionalengagement. For thispurpose the carrier plate 20 is pivoted as describedand is held toward the time wheel by the coiled spring 23.

The record strip is marked or calibrated as shown in Fig. L1, the centerlongitudinal line representing a dividing line between the indicationsfor and the normal condition and the transverse lines representing thetime.

Describing the operation of the mechanism and assuming that the lever isin its normal position as shown in Fig. 1 the pencil which is at alltimes in contact with the chart or strip will mark a line above thelongitudinal center line of the strip which in practice is a red line,it being understood that'the strip is continually moving. When the steamblows off the outer end of the lever is elevated and the inner end isdepressed with the result'that the niark of the pencil crosses the redcenter line and causes a line to be drawn therebelow whose length isdependent upon the length of time of the blowing-off of the steam. J ustas soon as the steam stops escaping the lever will drop to normalposition by reason of gravity and thereupon occupy its normal positionabove the red vthe blowing-off vcondition center line of the strip andthe pencil will cause a line to be drawn on the strip above the red lineof a length depending upon .the length of the duration of normalconditlon.

By reason of the time marklngs on the strip the exact time of theblowing-olf of the steam and of the normal or closed condition of thesafety valve may be determlned and 1n case t-he devlce is used on alocomotive it may be readily determined as to the loeality or localities.on the read Just Where the valve opened and closed and consequentlywhether the blowing-ofi' occurred during stops or on the run or atgrades, etc. The strip constitutes a permanent record of the efficiencyof the fireman and enables the employer to accurately determine suchefficiency. The construction and arrangement is such that the recordcannot be tampered with even though access may be.' had to the interiorof the casing inasmuch as the aggregate time traced by the pencil mustcorrespond to the time that the locomotive has been in service. Thestops 12 and 13 which limit the upward and downward os cillation of theleverl 9 provide for the straight line' tracing by the pencil eitherabove the center longitudinal line or below, as clear y shown in Fig. 4.I

In a device of the class described, the combination, with anescape valve for relieving excess pressure of steam, of recordingmechanism and a vane member located outside the steam passage andoperated by impact of steam escaping from the valve and arranged tocoperate with said mechanism to effect a permanent record of theduration of the escape of steam.

In a device of the class described, the combination, with an escapevalve for relieving excess pressure of steam, of recording mechanism anda lever located outside the steam passage, one end of which lever isformed as a vane lying in the path of steam'escaping from the valve andis moved thereby and the other end is in coperative relationship withsaid mechanism to effect a permanent record of the duration of escape ofsteam and of the normal condition of the valve.
